Oil Change

Let me explain something! Many years ago, a man named Fred Bersworth (I knew the family) came up with the formula for Ethamine, Diamine, Tetracetic acid. This is the formula for all detergents. The purpose of a detergent is TO HOLD STUFF IN SUSPENSION! It is not a Solvent! It will not dissolve sludge. The product being used with the detergent may contain solvent or naturally dissolve some of the sludge, but it's not the detergent. Flush the detergent oil out with the crap held in suspension and it's bye bye crap. And thats my story and I'm sticking to it! Other than that, I know nothing about chemistry. Google FC Bersworth,Chemical or EDTA,Chelates

Hi all,

I recently bought a 29 model a truck it came equipped with an oil pressure gauge. If I run less than 5 1/2 quarts in the pan it runs 0 oil pressure when tacking off and stopping. With 5 and half quarts of oil it doesn't happen. When it warms up pressure drops to 0 at stop lights. Any comments will be appreciated.

Thanks,
Joe
 
Those who use oil intended for diesels might like the information in this article:

Modern oils and modern engines are different than those in Henry's day, of course. We do some stuff to "upgrade" A engines, like insert bearings, but a lot of the old design features and materials will remain.

This is an interesting article with a short history of the development of lubricating oils, starting back in the early days of the steam era.

Warning: a lot of the nomenclature in the standards is really confusing.

Joe,

Gauge pressure shouldn't be used on a Model A as you would on a modern car. The Model A oiling system is very different than a pressure oil system.

Search the forum for info. My oil pressure gauge isn't really too useful.

The Oil Pressure gauge in my Ford 8n tractor was only slightly more useful. The O.P. went from 40+ lbs cold to under 5 lbs hot. Boy was that scary the first time!

Keep a Log Book.

It is very hard trying to remember what and when you fixed various things on your Model A. I strongly recommend keeping a small note book on everything you do to your car. I have two A’s and take care of a third for a friend. In each car, I keep a small book and write down everything I do. Things like oil changes, grease jobs, change points, new tires, new plugs, add lube to trans., pack water pump, check king pins, valve job, brake adjust or repair, etc. Anytime you do anything on your car, write it down. Show the date and mileage when you did it. This will let you know how long the points lasted, how long between spark plug cleanings, how many miles on your tires, oil change times, how often you had to add lube to the trans., last time you changed plugs or some other component. As I have problems, I describe what the problem is and what I did to fix it.
I have done this for years, and it has really paid off. If you have more than one car to keep track of, keeping such a log book is a must. I use those small, 3x5 in. ring note books that cost about $1.00. Keep a small pencil with it and always keep it with the car. When you go to sell the car, or hand it down to a new mechanic in the family, it will come in handy, and you will have all the history on your car since you had it.

Good advice, I've been doing that to all my vehicles, old and modern for over 50 years.
